vehicle fuel economy. Specifically, this study examines actual fuel economy of cars and light trucks (pickup trucks, SUVs, and vans) from 1966 through 2017. Calculated vehicle fuel economy is available going back to 1923. For 1966 through 1985, fuel economy was calculated from the information in a summary publication by the U.S.
According to the Federal Highway Administration, the average fuel economy for all light vehicles on the road today is 22.3 The Federal tax on gasoline is 18.4 cents per gallon, and each state has a gasoline tax, ranging from 8.95 Based on a vehicle with an average fuel economy of 22.3 cents in Alaska to 58.7
This analysis examines the effect of this downturn in driving on gasoline consumption (both total and per capita), and places the consumption in 2020 in a historical context. The results show that gasoline consumption per capita in 2020 was on par with that 55 years ago. Total consumption. Total consumption (millions of gallons).
NREL’s Fleet Test and Evaluation Team recently completed a year-long technology evaluation of gasoline hybrid electric (gHEV) FedEx Express delivery trucks compared with conventional diesel vehicles. On a drive cycle representing routes with frequent stops and accelerations, the gHEV trucks exhibited a 20% improvement in fuel economy.
California gasoline consumption rose 0.6% While more fuel efficient cars and trucks are increasing fuel economy—and in light of some of the recently improved economic statistics—consumers remain cautious in their spending as the economy continues toward an uncertain recovery. We’re in an uncertain time. per gallon, a 37.1%
The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent.
seen in 2010, according to the newly released BP Statistical Review of World Energy, 2012. Emerging economies accounted for all of the net growth, with OECD demand falling for the third time in the last four years, led by a sharp decline in Japan. in the emerging economies. Global energy consumption grew by 2.5%
the E30 and E78—led to statistically significant reductions of 9%–13% for total hydrocarbon (THC); 13%–44% for non-methane hydrocarbon (NMHC); 20%–35% for carbon monoxide (CO); and 17%–36% for nitrogen oxides (NO x ) emissions compared to the high-aromatics E10 fuel. Their paper is published in the ACS journal Energy & Fuels.
Also, the list of standard test procedures addressed in SAE J1711 has been expanded to cover all five major test cycle procedures (UDDS, HFEDS, US06, SC03, and Cold FTP) now being used to evaluate vehicle fuel economy. gasoline and Diesel fuel), alcohol-based liquid fuels (e.g., Earlier post.) compressed natural gas).
While alternative powertrains still represent a small percentage of market share compared to gasoline engines, the report noted, clean diesels saw a 10% increase in 2014 sales over 2013 sales, while hybrids saw a 10% decrease, pure electrics saw a 20% increase and compressed natural gas saw a 33% decrease.

The paper is published in the journal Nature Energy. —Alan Jenn.
Gasoline production was up from the prior month, but was down from the prior year and the prior year-to-date. In October, gasoline production reached the second highest output for the month of October, up 3.5% For year-to-date, gasoline production decreased 1.5% —API Director of Statistics Hazem Arafa.
The morning session started out with an hour long press conference, the highlight being the unveiling of the Volt’s 230 mpg preliminary EPA city fuel economy finding ( earlier post ), as well as a tour showing selected elements from the studios of the four GM North American brands: Chevrolet, GMC, Buick and Cadillac. Focus on fuel economy.
Empirical results also revealed that even if the fuel economy of less fuel-efficient ordinary passenger vehicles were improved to levels comparable with those of the best available technology, i.e. hybrid passenger cars currently being produced in Japan, total CO 2 emissions would decrease by only 0.2%. —Kagawa et al.
The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
The project led by Tang-Wei Kuo from General Motors is focused on optimizing multi-hole injectors for spark-ignited direct-injection (SIDI) gasoline engines. Recently, the most popular SIDI gasoline injectors have been multi-hole type. Co-investigators are Ronald Grover (GM), Sreekanth Pannala (ORNL), and Wael Elwasif (ORNL).
The developed prototype must be capable of demonstrating a net 10% fuel economy improvement, and cost to manufacture on a production basis must not exceed $200/unit. Statistically valid fuel economy improvements (95% confidence level) of at least 5.0% Reciprocating internal combustion (e.g. are desired.
This statistic increases to two-thirds of all new registrations if the data are restricted to passenger cars, according to Bosch. This offers potential for growth given the country’s steadily expanding economy. Their place is taken by vehicles that run on pure ethanol or on a mixture of ethanol and gasoline (FlexFuel).
Which are the alternative fuels for cars that could replace gasoline in vehicle? The fossil fuels are highly significant in the global economy. Let’s see a quick statistic. Methanol can be used in internal combustion engines either directly or as a blend with gasoline. You can guess it easily. It is not a low value.
liter gasoline unit combining turbocharging, direct fuel injection and VALVETRONIC fully-variable valve management; a new 3.0-liter liter gasoline unit combining turbocharging, direct fuel injection and VALVETRONIC fully-variable valve management; a new 3.0-liter Liter Straight-Six Gasoline Engine with TwinPower Turbo.
Growth Energy, an ethanol industry trade group, petitioned the EPA in March 2009 to raise the limit on ethanol in gasoline from 10 to 15 percent. Only three out of the eight engines were tested with straight gasoline containing no ethanol (E0), and one of those three failed the CRC’s test. Background.
billion into the US economy annually. No statistically significant change was detected. Moving to higher ethanol blends will help build on the foundation established by today’s ethanol to ensure a viable market for tomorrow’s advanced ethanol that can reduce greenhouse gas emissions by up to 86 percent compared to gasoline.
Using statistical methods, the scientists infer emissions from these data within a radius of about one kilometer of the measurement location. Generally, different combustion and exhaust treatment characteristics result in significantly higher NO x /CO 2 emission ratios for diesel powered cars than for gasoline. —Thomas Karl.
percent share of the market earlier this year — we’ve yet to see any statistical analysis putting plug-in hybrids above 1.9 In the past year, virtually every major automaker has made a pivot to PHEVs as a bridge between gasoline-powered vehicles and fully electric vehicles. percent with battery only models representing 9.4

The research teams have identified more than 40 promising blendstock candidates. Click to enlarge.
It appears that demand for gasoline (petroleum) in the US is more sensitive to higher prices and the effects of the sluggish economy than expected after deliveries in May hit their lowest levels since 2003. According to the American Petroleum Institute’s Monthly Statistical Report, deliveries in the month dipped 0.4
gasoline or diesel) engines for automotive applications use slider/crank mechanisms to create torque on an engine’s output shaft from forces applied to pistons as a result of the pressure created by the combustion of fuel. Statistically valid fuel economy improvements (95% confidence level) of at least 4.0% are desired.
With the economy still struggling to recover, US gasoline deliveries during the first half of 2010 were 0.6 The American Petroleum Institute Monthly Statistical Report revealed that June deliveries reached 9.18million barrels per day – the lowest level for June [.].
Concerns centered around the ailing economy, which has been undermined by higher interest rates and ongoing inflation. He did say that statistics suggest the momentum for its battery-electric EQ vehicles is building. “In But the all-electric EQB 250 (the brand’s cheapest EV) starts at $52,750 under the same conditions.
BYDs elegant, money-saving use of lithium iron phosphate battery cells makes the 947-kilowatt (1,287-horsepower) U9s price point possible and also allows the company to sell a plug-in hybrid that undercuts the prices of stalwarts at the economy end of the market including the Toyota Corolla. And robotaxis are leading the charge.
Although the EPA has not as of this writing released the final fuel economy numbers for the US A3 e-tron, Filip Brabec, Director, Product Management, Audi of America, said that the figures will be around 83 to 86 MPGe combined (depending on the equipment level), with 35 to 39 mpg gasoline only and 16-17 miles of EV range.
For example, fuel economystatistics and a graphic display of the electric range is shown on the navigation map. The Q7 PHEV will arrive in dealerships in Germany in 2016, and will likely come to the US, although perhaps with a gasoline-engine variant. US gal) of gasoline. Audi e-tron quattro concept SUV. liters (1.0
The statistics can differ depending on how much sunlight each location receives each year. The SUV is equipped with a solar roof, electricity-generating sidelites, peer-to-peer charging, regenerative braking, and fold-out solar array ‘wings,’ according to Humble Motors.
Though the PHEV combines the two types of energy and power, it is not merely a temporary “transition” between gasoline and diesel cars to pure electric cars. Since it can refuel from a standard household outlet and from a gasoline station, it needs no new infrastructure. Appendix D: Vehicle Driving Statistics. slow charge.
And I’ll go back to something several years ago: that in the future, gasoline cars that are not autonomous will be like riding a horse and using a flip phone, and that will become very obvious in hindsight. There is no meaningful limit to the size of the economy. So that’s that’s what’s going to happen.
